Figure 3

Seasonal variation in the rate of frontogenesis. Contribution of oceanic (red; the second term on the right hand side of Eq. (3)) and surface heat flux (blue; the first term on the right hand side of Eq. (3)) terms to the frontogenesis (black; the left hand side of Eq. (3)) from October to April at 145°E–150°E (in °C °latitude⁻¹ month⁻¹). A positive (negative) rate of frontogenesis indicates frontogenesis (frontolysis). The figure was prepared with Kaleida Graph 4.0.
